过去一般时态的原理,一、过去一般时态的构成：,1.判断动词be:,(1)肯定句主语+was或were+表语+状语.Hewasastudenttenyearsago.,(2)否定句主语+was或were+not+表语+状语.Hewasnotastudenttenyearsago.*was+not=wasnt*were+not=werent,(3)一般疑问句Was或Were+主语+表语+状语?Washeastudenttenyearsago?,（4）特殊疑问句A.疑问词（作主语）+was/were+表语+状语?Whowasateachertenyearsago?Whatwasinfrontofthehousetenyearsago?,B.疑问词（不作主语）+was/were+主语+.?What（表语）washetenyeasago?状语,2.行为动词和其他判断动词:,(1)肯定句主语+行为动词过去式或其他判断动词过去式+.HeboughtanMP4yesterday.,Ibecameateachertwentyyearsago.,*英语中的绝大多数动词是规则动词，个别动词是不规则动词。规则动词的过去式=该动词的原形+-ed;不规则动词的过去式有特殊形式（见“不规则动词表”）。,(2)否定句主语+didnot+行为动词原形或其他判断动词原形+.*did+not=didntHedidnotbuyanMP4yesterday.Ididnotbecomeadoctor.Ibecameateacher.,(3)一般疑问句Did+主语+行为动词原形或其他判断动词原形+?DidhebuyanMP4yesterday?Didyoubecomeadoctortenyearsago?,（4）特殊疑问句A.疑问词（作主语）+行为动词过去式或其他判断动词过去式+?WhoboughtanMP4yesterday?,B.疑问词（不作主语）+did+主语+行为动词原形或其他判断动词原形+?Whatdidhebuyyesterday?,3.“Therebe句型”的过去一般时态:,(1)肯定句There+was或were+主语+状语.Therewasatalltreeinfrontofourschooltenyearsago.,(2)否定句There+was或were+not+主语+状语.Therewasnotatalltreeinfrontofourschooltenyearsago.,*was+not=wasnt*were+not=werent,(3)一般疑问句Was或Were+there+主语+状语?Was或Were+there+atalltree+infrontofourschooltenyearsago?,（4）特殊疑问句A.疑问词（作主语）+was/were+表语+状语?What+was+infrontofourschool+tenyearsago?主语表语状语,B.疑问词（不作主语）+was/werethere+主语+.?When+wasthere+atalltree主语infrontofourschool?地点状语,二、过去一般时态的定义用法,1.概括叙述过去的事情，概括叙述过去发生了什么事。2.概括叙述过去的一般状况。,*过去一般时态的“过去”可以很具体，可以不太具体，也可以很模糊。【例1】IsawJaneandherboy-friendintheparkat8oclockyesterdayevening.（时间很具体）(但不展开过程）,【例2】HeboughtanMP4yesterday.(时间不太具体)（概括叙述）【例3】IoftentookcoldbathswhenIwasyoung.（时间很模糊）（概括叙述过去的一般状况）,*只有一个“过去”，用过去一般时态或过去进行时态。YesterdayIhadwatchedabasketballmatch.()YesterdayIwatchedabasketballmatch.(),*一连串的、紧接着发生的过去的动作，都用过去一般时态，不再区分先后。【例4】Hurriedly,shedroppedaglassofmilkonthefloor,soshehadtocleanit.Thenshegotherhandbagandhurriedout.,【例5】Thekingheardthemusicfromhiswindow,andsummonedthegirltothepalace.,*两个过去的动作A和B，如果A发生在B的过程中，那么，A用过去一般，B用过去进行。Iwasplayingthepianowhenhecamein.,*“过去一般时态”的动作或状态，对“现在”（此时此刻）来说，都是“完成了的”。但“过去一般时态”仅表“过去”，看不出“现在”（此时此刻）的状况”。而现在完成时态，用过去说明现在，能看出现状。,Thedoctorsavedtheboy.Theboyistalkingwiththedoctor.()Thedoctorhassavedtheboy.Theboy
